On Tuesday, a 39-year-old man was punched in the face and robbed of his cellphone while riding the T-Third line in the area of Third and Gilman, police said. About five suspects are being sought in the assault, which occurred just after 8:30 p.m.

The victim suffered bruises to his face and declined medical treatment, police said.

Also, early Tuesday morning, a dispute on a bus led to a stabbing in the 3000 block of Mission Street, police said.

Two men threatened to kill a 47-year-old man “because they felt they were disrespected” on the bus. After a fight, one of the suspects, described only as men in their late 20s, stabbed the victim in the chest and back, police said.

His injuries are not life threatening, police said. There has been no arrests.

Despite the recent violence, police told The San Francisco Examiner Tuesday that crime overall is down 7 percent on Muni. The recent activity is “very unusual,” police said.
